Malfing: a depraved, necrophilic, sexual act that involves digging up a freshly buried female corpse that has decayed but whose body cavity has not yet burst and setting it on a table and placing one's mouth on the vagina/vaginal/anal region whilst another jumps on the stomach of the corpse thus expelling with great force putrified organs/fluids into the mouth of the receiver to the enjoyment and pleasure for all those involved.

Receiver: Dude, will you come with me to go malfing tonight?
Jumper: Yeah, they just buried a lady 2 days ago and she should be ripe for the picking.
